The training hall was calibrated to mimic the time ratio of Dungeons. However, the Chuunibyou Society was unable to replicate all of the effects, so the ratio was reduced. Instead of a 1:1 day-to-hour ratio, the hall made it 10 hours:1 hour. In essence, for every ten hours spent in the training hall, only one hour passed in reality.
"Now I understand why they made such a big deal out of my being late," Matt thought to himself. "Just how long were they training and waiting for me? Or maybe they turned off the time ratio setting. That would be more realistic..."
In any case, Matt had no idea how long he had been training. He only knew he had spent hours working and taking occasional breaks. When he got hungry, he went out to the lobby, where he found vending machines that dispensed snacks for free.
